Space Jam is the pin that I've had the longest, and was my first pin. Got a good deal on it from a local barcade owner during the pandemic and the future of arcades was iffy at best. Dude needed to make some money to keep lights on, and sold his personal Space Jam (mine). So this review is right around three years into owning it.
Mine's shopped out with LEDs and I believe some additional GI lighting. It's nice, and a good candidate for LEDs in general, but I will say there's an "AC hum" that you hear all the time during attract mode. Chased that like crazy, and annoys the heck out of me. I've heard from a couple people that Sega pins pretty frequently do that with LEDs. Can't knock the title as a whole for that, but it's worth mentioning if you're going to retrofit one.
Layout is pretty nice. If you've played a Stern NBA, it's 95% the same game. Plays pretty quick, nice geometry in general and pretty nice selection of shots. It's not slow, and it's not brutally fast. Center post between the flippers helps with a lot of awkward drains from the pop bumper/drop target area.
Rules...leave something to be desired. The balance is such that I've yet to have a game that felt like I got any points from anything besides multiball. The multiball action itself is great, from the lock mechanics to the callouts to the progressive rules throughout multiball. It's really hard to get through the super jackpots, and it does not save progress between multiball attempts. With each multiball becoming progressively more difficult to achieve, this is a bit frustrating to me, especially when so much of one's score is dependent upon the multiball. I have yet to get to the wizard mode, which means there's a bit of replayability to it...but there's not a lot of payoff on the way points-wise.
Art is decent. Backglass is nice and recognizable, and it's definitely MJ-heavy. The Sega lenticular backbox does look cool. I'm fairly pleased with the aesthetics, and Space Jam was a definite favorite of mine as a kid. It does the license a fair amount of justice, but could have leaned much heavier into the source material. What I mean is that, yes, there are shots and modes that feature Looney Tunes characters, but for the most part aren't really specific to the characters or do them any real justice. And there are a LOT of missed opportunities with all the great characters in the Looney Tunes cast and the Monstars and all that. I wish it were more Looney Tunes-themed and less basketball-themed, just to offer some more variety.
The DMD animations are surprisingly nice, with some basketball "footage" looking really nice in moments like hitting the magnetic hoop off that left ramp (which is honestly a really fun and satisfying mech). Sound is pretty good too. Callouts can be a little annoying, depending on what you're hitting the most frequently. But, having a decent variation between modes and such in your game would help with this.
One speech thing that drives me INSANE is that, upon starting the game, a sportscaster (maybe the mouse from the movie, but if not is a decent soundalike) announces Michael Jordan like they would at the start of an NBA game....except...Jordan was a point guard. For WHATEVER reason, the announcer says "pit guard". I have to think he was reading his lines off a script and it was abbreviated "pt. guard" so he misread it. Seriously, seriously annoying.
One speech thing that I love is that Tweety taunts you when you lose your final ball; "Aww...did we wose ouw baww down da dwain?". It gets under your skin just the right amount, and hitting both flippers has Sylvester come into frame and chomp down on Tweety. Super clever and a super appreciated touch.
Overall, I don't dislike the game. I don't love the game. For the $2,600 I paid for it, I'd have rather dropped another grand and gotten an Earthshaker, no question. Or a few hundred more on a World Poker Tour. Or, $2,600 toward a Cactus Canyon Remake or something.
But, it is fun, it's a decent use of the license, and it's worth at least a few credits if you find one on location. And if you're absolutely bananas for the theme, you'll probably really enjoy it on the whole.
